A mask generation function takes an octet string of variable length and a desired output length as input, and outputs an octet string of the desired length. The plaintext-awareness of RSAES-OAEP relies on the random nature of the output of the mask generation function, which in turn relies on the random nature of the underlying hash. :param bytes seed: seed from which mask is generated, an octet string :param int length: intended length in octets of the mask, at most 2^32(hLen) :param str hasher: hash function (hLen denotes the length in octets of the hash function output) :return: mask, an octet string of length `length` :rtype: bytes :raise OverflowError: when `length` is too large for the specified `hasher` :raise ValueError: when specified `hasher` is invalid z=Invalid `hasher` specified.
